1.2 General precaution
DO NOT expose the inverter to the dust, rain, snow or liquids of any type, it is designed for
the indoor use. DO NOT block off ventilation, otherwise the RiiO Sun All in One Solar
Inverter would be overheating.
To avoid the fire and the electric shock, make sure all cables selected with right gauge and
connected well. Smaller diameter and broken cable are not allowed to use.
Please do not put any inflammable goods near to the inverter.
NEVER place the unit directly above batteries, the gases from the battery will corrode and
damage the RiiO Sun All in One Solar Inverter.
DO NOT place battery over RiiO Sun All in One Solar Inverter.
1.3 Precaution regarding battery operation
Use plenty of fresh water to clean in case the battery acid touches the skin, the clothing, or
eyes and consult with doctor as soon as possible.
The battery may generate flammable gas during charging. NEVER smoke or allow a spark
or a flame in the vicinity of the battery.
DO NOT put the metal tool on the battery, a spark and a short circuit might lead to a
explosion.
REMOVE all personal metal items such as rings, bracelets, necklaces, and watches while
working with batteries. Batteries can cause short-circuit current high enough to make metal

2.3 Function
2.3.1 Power Control and Power Assist
RiiO Sun offers a unique feature of power control & power assist, which is very useful when you
have a limited grid supply or working with the generator. RiiO Sun will take control of energy flow
automatically, using extra power to charge the battery or inverting as the supplement to the grid or
generator. With this feature, you can avoid the air switch trip and do not have to use oversize
generators.
2.3.2 Powerful and Reliable Inverter
High Performance Pure Sine Wave
RiiO Sun is a pure sine wave inverter generating a near perfect sinusoidal AC wave power output
that is very similar or even better to what you can get from your utility grid. Pure sine wave can
guarantee the correct function of the sensitive equipments (computer, laser printer, TV, etc.). Also,
your home appliances such as fridge, microwave and power tools will work more efficiently.
High Surge Power Capability
Provided with outstanding surge power capability and low frequency transformer, RiiO Sun is
suitable for heavy inductive load like fridge, coffee maker, microwave, power tools, air conditioner,
etc.
Battery Low Voltage/SOC Protection
RiiO Sun provides configurable battery low voltage/SOC protection.
2.3.3 Professional Battery Charger
Multi Stage Sophisticated Charging Algorithm for Lead Acid Battery
Fitted with multistage charging algorithm (bulk-absorption-float-recycle), the built-in charger of the
RiiO Sun is designed to charge battery quickly and fully. Microprocessor controlled charging
algorithm with variable absorption charging timer could guarantee the optimal charging for the
batteries of different discharged states.
Figure 2-6 Multi Stage Sophisticated Charging Algorithm for Lead Acid Battery

RiiO Sun User Manual

Float charging and recycle charging program guarantee your battery getting proper maintenance
in case of long time connected and less aging in case of long time connected with no use.
Multi Chemical Batteries Available
RiiO Sun offers premium charging algorithm for the common chemical acid batteries including
AGM, GEL, Flooded, lead-carbon and Lithium battery. You can set the battery parameters through
the LCD interface and the TBB Link software.
Lithium Battery Compatible
RiiO Sun has built in communication protocol compatible with for Super L lithium battery from
TBB.
Manual Equalization
It is strongly recommended to read this section carefully before you start the EQ
charging and Don’t leave the battery unattended while performing desulfuration.
Always check if you’re the battery supplier recommend the EQ charging. Only start
when it is suitable.
If the battery type was set at AGM, GEL or Lead-Carbon , this charging profile can’t
be triggered on.
Over a period of time, the cells in a flooded battery can develop uneven chemical states. This will
result in a weak cell which in turn can reduce the overall capacity of the battery. To improve the life
and performance of the flooded battery, RiiO Sun provides a manual equalization program that
can be used. If it is recommended by the battery manufacturer, you can initiate the desulfuration
program manually. Once you trigger on the equalization program, the RiiO Sun will perform
equalization charging.
After 30 minutes, it will quit EQ and enter into float charging.
Check the electrolyte level and refill the battery with the distilled water if necessary.
If you want to come to normal charging, you need to stop equalization charging and switch off
the unit.
Switch on the unit again, then you will have your equipment back to normal charging.
During equalization, the battery generates potentially flammable gases. Follow all
the battery safety precautions listed in this guide. Ventilate the area around the
battery thoroughly and ensure that there are no sources of flame or sparks in the
vicinity.
Turn off or disconnect all loads on the battery during equalization. The voltage
applied to the battery during equalization may be above the safe levels for some
loads.
Frequency:
Maximum once a month, for heavily used battery, you may wish to equalize your battery. For
battery with light service only need to be equalized every 2-3 months.

RiiO Sun User Manual

Important:
Equalization may damage your batteries if it is not performed properly. Always check battery
fluid before and after equalization. Fill the batteries only with the distilled water.
Always check the equalization switch is set back to OFF after each time’s equalization.
Follow the battery manufactures’ recommendations on equalization vary. Always follow the
battery manufacturer’s instructions to properly equalize the batteries. According to the guide,
a heavily used battery may require equalization once a month while a battery in light duty
service only needs equalizing once every 2 to 4 months.
Battery type:as a kind of protection, equalization charging can be performed if and only if you
set the battery to be a traction, Flooded /OPzV batteries. If you choose the AGM, GEL or
Lead-Carbon, EQ charging can’t be performed.
2.3.4 Transfer
Uninterrupted AC Power
In case of voltage/frequency/waveform of AC input match the minimum quality, the voltage will be
switched directly to the AC output. The RiiO Sun All in One Solar Inverter will work as a battery
charger and the loads will be powered by AC input. The voltage of the AC output and the AC input
will be the same.
In case of the AC input failure or excessive AC input current set by the user, the RiiO Sun All in
One Solar Inverter will initiate a quick switching to the inverter, which will guarantee an
undisturbed power. Once the AC input resumes or matches the quality, it will switch back again.
Due to its ultra quick transfer design, as quick as 4ms, RiiO Sun All in One Solar Inverter could be
used as an UPS.
2.3.5 Protect Function
The RiiO Sun All in One Solar Inverter is equipped with a series of complete hardware and
software protection functions to ensure its stable and reliable operation.
Overload Protection
When overload protection is triggered on, it will restart automatically after 60s. And after three
consecutive overload shutdown protections, the equipment will not restart automatically. At this
time, the user needs to manually restart.
Over Temperature Protection
When the internal temperature is too high, RiiO Sun will enter into the over-temperature protection.
After the internal temperature returns to normal, it can automatically resume normal operation.
Short Circuit Protection
The equipment will automatically shut down when the AC output is shorted and needs to be
manually activated.
Battery Low Voltage/SOC Protection
To prevent the permanent damage caused by the over discharge of battery, the equipment will
automatically cut off the output according to the low voltage/SOC protection point set by the user.

2.3.6 Communication
Dry Contact Input
RiiO Sun is equipped with a dry contact input for remote on/off control.
Note: When the setting item 64 Main switch selection is set as Mobile Only mode, the touch
switch needs to be changed to a rocker switch.
RS485
Equipped with two RS485 interfaces.
ComSYS: System communication(RS485), connected to SP or BGK.
ComMON: RS485 port for external monitor such as MCK, SNMP, Kinergy, etc.
2.3.7 ECO Mode
ECO Mode is to reduce the output power of the inverter while maintaining the normal use. When
the battery capacity is insufficient or the SoC is in a low value, by setting the ECO Mode in the
inverter, the power consumption of some specific loads can be reduced by 45% at max (30% on
average), thereby prolonging the battery life.
